No. 6r is 6 multiplied by r so in order to get r, you will need to divide both sides by 6 in the first equation so r should =12
Each one would be 5 minutes because 2 1/2 Times 4 = 10 minutes. You would have 20 minutes remaining so divide 20 by how many segments there are, which is 4 to get 5
Answer:
x^9
----------------
125 y^12
Step-by-step explanation:
(5x^-3 y^4)^-3
We know that (ab)^c can be split into a^ * b^c
5^-3 *x^-3 ^-3* y^4 ^-3
We also know that a^b^c = a^ (b*c)
5^-3 *x^(-3 *-3) * y^(4 *-3)
5^-3 *x^(9) * y^(-12)
We know that negative exponents in the numerator move it to the denominator. The exponent stays the same except for the negative.
1/5^3 * x^9 * 1/ y^12
We know that 5^3 = 125
Rearranging the order
x^9
----------------
125 y^12
the fraction is 60/100 or in sipulist form 6/10 as a desimel of tenths it would equel .6
A. 3 days a week: 12/80=0.15
B. MORE than 4 days a week: 28/80= 0.4625
C. at LEAST once a week: 0.8125
Correct.
